- Abstract
- Five rare-earth metal containing quaternary phosphides in the RELixCu2-yP2 (RE = La, Pr, Nd, Gd, Er; 0.82 <= x <= 1; 1.19 <= y <= 1.54) series were synthesized by using high-temperature synthetic methods, and they were characterized by single-crystal X-ray diffraction. The title compounds crystallize in the trigonal space group P (3) over bar m1 (Z = 1, Pearson code hP6) with four crystallographically independent atomic positions. The overall crystal structure can be described as a Li-filled CaAl2Si2-type structure, in which a partially occupied Li site is embedded within the double-deck layers formed by two anionic components. Tight-binding linear muffin-tin orbital calculations including density of states, crystal orbital Hamilton population, and electron localization function analyses provided rationales for the overall electronic structure and chemical bonding of the title phase. PrLi0.98(5)Cu1.54(1)P2 indicated an antiferromagnetic interaction of Pr at a relatively low temperature with a paramagnetic Curie temperature of -6.8 K and a thermal conductivity of 3.2 WmK(-1) at 323 K.
